By comparing a clearly defined visual input with the electrical output of the retina, researchers at the Salk Institute for Biological Studies were able to trace for the first time the neuronal circuitry that connects individual ...

(PhysOrg.com) -- Plasticity -- the brain's ability to change in response to external input -- is critical for most cognitive functions, including learning and memory. Those changes usually involve a strengthening or weakening ...

(PhysOrg.com) -- Cases of restored vision after a lifetime of blindness, though exceedingly rare, provide a unique opportunity to address several fundamental questions regarding brain function. After being deprived of visual ...

The portion of the brain responsible for visual reading doesn't require vision at all, according to a new study published online on February 17 in Current Biology. Brain imaging studies of blind people as they read words ...

(PhysOrg.com) -- The most striking feature of jumping spiders is their arsenal of big eyes. In contrast to web-building spiders, they rely on their excellent vision to actively hunt and catch their insect prey. New research ...

(PhysOrg.com) -- An earthquake machine has been used by vision scientists to confirm that instead of working in isolation, our visual and middle-ear systems work together, to give us an improved sense of balance.

In macular degeneration, the most common form of adult blindness, patients progressively lose vision in the center of their visual field, thereby depriving the corresponding part of the visual cortex of input. Previously, ...

Normal vision is essentially a spatial sense that often relies upon touch and movement during and after development, there is often a correlation between how an object looks and how it feels. Moreover, as a child's senses ...

How do the visual images we experience, which have no tangible existence, arise out of physical processes in the brain? New research at the Weizmann Institute of Science provided evidence, for the first time, that an 'ignition' ...

Brain and spinal-cord injuries typically leave people with permanent impairment because the injured nerve fibers (axons) cannot regrow. A study from Children's Hospital Boston, published in the December 10 issue of the journal ...
